Evacuation systems typically consist of manual pull stations, horn strobes and strobe units. These systems are designed to trigger an audible alarm and visual alarm when it is necessary to evacuate the building. The alarm is manually activated by the use of a manual pull station to trigger the system.

Fire alarm systems can include alarm initiating devices, alarm notification appliances, control units, fire safety control devices, enunciators, power supplies and wiring. These systems have helped save millions of lives.  One drawback however, is that such a system can be disrupted by deliberate false alarms.

Voice evacuation systems are similar to public address systems in as much as it can provide announcements, music, shift change tones, etc. Where it differs is that the entire system is designed to continue to function even though everything else may be failing.

This covers all aspects of the system from the type of cable used and how it is installed to the provision of redundant amplifiers on standby waiting to fill the gap should an amplifier fail.

A well installed system will provide automatic clear and concise instructions to anyone in the building in the event of an emergency.

When a fire alarm sounder or bell operates, people tend to look at the person next to them and ask "Is this a drill?" or "Are they testing the system?" As if the stranger next to them will know!

When a voice alarm operates, people just get up and leave the building.
